I wanted to start a new thread just trying to get more at the heart of full spectrum videography. Perhaps we will have a line of threads with similar titles and names as the research continues. I'm adding more 2 cents and trying to organize the thoughts as I go. Opinions welcome, positive and negative of course.
Nearly everything mentioned here is a bunch of things you shouldn't ever do.
**OFF THE SHELF**
The simplest and one of the lowest price point solutions for this type is a ghostcam for $200-
But this ghostcam seems more for Infra-red than it is for Ultraviolet. Preferably we want something that does all 3: Infrared, visible, and ultraviolet.
**DIY GENERAL CAMERAS**
You'll notice that dSLRs are usually VERY complicated to convert to full spectrum. Interesting that they manufacture it that way. You would think they could have engineered it to just have the front piece disassemble to get at the filters. Instead, you need to gut out the entire machine from back to front before you get to one of the very last pieces. It is indeed a huge risk of damaging the camera, and probably takes all day to do carefully. Maybe it's a sign the powers that be really don't want you going there.
Most cameras SLR, video, etc, seem to convert this way. You have to dig through the very depths to get to the Hot Mirror. And in some cases, you need to replace it with a clear glass in order for it to work again.
Conversion as shown here.
**SEND IN YOUR CAMERA**
If you bring any camera to Life Pixel, they will convert it. Not for cheap, but professionally, reasonably. Of course, this does not necessarily work with the manufacturer's warranty.
It's worth noting that you can still use a converted camera back to its original form by either reinstalling the lens or adding the lens as an external filter.
Finally, and I have no idea if this works, is you put in a webcam. Only the Sony Eye 3 is what I found so far that comes cheap and works at 60fps.

This talks about converting one DIY (since you're trying to go the cheap route)
And install a driver on your PC to make it work like a regular webcam-
This man converts his Hero 3. Near the end he actually breaks the glass. I'm sure there's a way that doesn't actually break it.
